Yes, thank you both, and your fellow collectors at the meeting. This is like cool water to a man in the desert to me!
If I understand #4 correctly, Ayutthaya daab have a more uniform width (meaning edge-to-spine) than Ratanakosin daab? Looking the other way, Ratanakosin daab bulge out more toward the tip?
The PaGan is an interesting feature. Is it something that you can only see when the handle is removed? There is not one visible on my Ayutthaya daab (
